采用小结构模型试验方法研究了带有横缝拱坝的动力特性和动力响应。试验模拟了拱坝的无缝、局部有缝和全缝三种不同的构造,分析探讨了关于分缝拱坝的动力性态的变化规律,并用相应的线性和非线性有限元法进行了计算比较,取得了基本一致的变化规律.对强震激励下的横缝破坏机理作了分析讨论。
A small structural model test is used to study the dynamic characteristics and dynamic response of arch dam with transverse joints. The test simulates three different structures of the arch dam, which are seamless, partially sewed and fully seamed. The variation of the dynamic behavior of the arch dam is analyzed and discussed. The corresponding linear and nonlinear finite element methods are used to calculate Compared with the same method, and obtained the basically consistent change rule.Analyzing and discussing the mechanism of transverse joint failure under strong earthquake excitation.
